 adjacent riparian habitat in Idaho. Res. Pap. INT-445. Ogden, UT: U.S. Department of 

 Agriculture, Forest Service, Intermountain Research Station. 4 p. 



Small mammal populations and community organization were compared between a 

 beaver pond habitat dominated by willows and an adjacent nonwillow riparian habKat. 

 Small mammal relative density was 3.06 times higher and standing crop biomass was 

 2.71 times higher in the beaver pond habitat than in the adjacent nonponded habitat. 

 There were no pronounced differences between the two habitats in small mammal species 

 richness or species diversity. 



KEYWORDS: density, diversity, standing crop biomass, rodents, shrews, populations, 

 Salix spp.
